Thaum lub twj tso kua mis hydraulic poob qis dua 350-bar siab, tus neeg ua txhaum tsis tshua muaj vaj tse lossis foob - nws yog Stellite ntsaws. Tsis yog ib qho plug xwb. Ib qho nrog qhov tseeb 0.005 hli concentricity, AMS 5387-raws li cobalt matrix, thiab xoom micro-kawg tom qab kev kho cua sov. Yog vim li cas engineers hauv Houston, Hamburg, thiab Singapore tsis nrhiav "cobalt alloy plugs." Lawv nrhiav ib Stellite plug Hoobkas uas ships feem - tsis tau cog lus.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. tau muab cov khoom ntawd txij li xyoo 2012. Tsis yog los ntawm phau ntawv teev npe. Los ntawm lub ntiaj teb tsis ua hauj lwm tsom xam: tawg nozzles nyob rau hauv offshore txhaj tshuaj twj tso kua mis, galling ntawm winch center ncej chais nyob rau hauv Arctic-qib engineering tsheb, ntxov ntxov hnav nyob rau hauv high-cycle piston twj cylinder vaj tse. Peb tau pom txhua hom kev ua tsis tiav - yog li peb siv txhua lub Stellite ntsaws kom tshem tawm lawv ua ntej lawv pib.
Ntawm no yog dab tsi cais cov ntsaws ruaj ruaj los ntawm ib qho uas kav ntev li 3 × ntev hauv kev pabcuam: kev tswj kev siv hlau, tsis yog kev ua haujlwm raug. Cobalt-raws li T800 thiab AMS 5387 tsis yog "nyuaj rau lub tshuab" - lawv yog * tsis zam txim * yog tias koj txiav txim siab thermal expansion thaum ua tiav los yog hla cov tshuaj annealing ua ntej sib tsoo. Ntawm peb qhov chaw ISO-certified nyob rau hauv Qingdao, txhua Stellite plug pib nrog traceable, ntawv pov thawj raw cov ntaub ntawv-tsis muaj ntawv pov thawj zeb txais tsis muaj spectral pov thawj. Peb khiav cov khoom tuaj los ntawm OES kev tshuaj xyuas, tom qab ntawd muab txhua lub tshav kub ntau tus ID nkag mus rau hauv peb qhov ERP system. Yog tias tus neeg siv khoom qhia txog qhov tsis txaus ntseeg ntawm Lot #QS-24-8817, peb rub cov ntaub ntawv tag nrho: cov txheej txheem casting, CNC toolpath cav, CMM scan cov ntaub ntawv ntawm 32 cov ntsiab lus tshuaj xyuas, nto roughness (Ra ≤ 0.4 µm), thiab tom qab cua sov-kho hardness (42-48 HRC, txheeb xyuas peb qhov chaw ib feem). Tsis muaj kwv yees. Tsis muaj batch nruab nrab.
Qee tus yuav sib cav tias cov khoom ntawm Stellite tawm ntawm lub txee yog pheej yig dua. Tab sis tus nqi tsis suav ntawm qhov kev yuav khoom - nws ntsuas hauv lub sijhawm poob. Ib qho $ 210 ntsaws uas ua tsis tau tom qab 4,200 lub voj voog raug nqi ntau dua $ 390 ntsaws rau 14,500 lub voj voog thaum koj cov khoom siv sab nrauv poob 18 teev lub sijhawm txhaj tshuaj. Qhov phem tshaj: cov neeg muab khoom lag luam feem ntau hloov Stellite 6 nrog pheej yig dua cobalt-nickel blends tsis muaj chromium carbide dispersion xav tau rau erosive slurry ib puag ncig. Peb tsis hloov. Peb sim. Txhua lub ntsaws raug kuaj tshuaj ntsev (ASTM B117, 500 teev), hydraulic pov thawj siab (1.5 × ua haujlwm siab, tuav rau 10 feeb), thiab tshuaj xyuas ultrasonic ib ASTM E114. Yog tias nws tsis dhau tag nrho peb, nws tau muab pov tseg - tsis rov ua haujlwm dua.
Peb kuj daws qhov uas feem ntau cov chaw tsim khoom yuav tsis lees txais: geometry txwv. Standard Stellite plugs xav tias cov ntaub ntawv cylindrical yooj yim. Cov ntawv thov tiag tiag xav tau eccentric bores, asymmetric sealing lub xub pwg nyom, los yog kev sib xyaw ua ke ntawm cov dej txias ua tshuab rau hauv tib lub teeb. Peb 5-axis milling centers lis contours uas yuav tsum tau peb setups lwm qhov-txo cumulative yuam kev thiab tshem tawm re-fixturing distortion. Rau ib lub twj tso kua mis European OEM, peb rov tsim dual-orifice Stellite plug nrog offset flow paths thiab 0.012 hli phab ntsa tuab ntawm cov chaw nres nkoj. Thawj tus neeg muag khoom tau hais tawm 14 lub lis piam thiab tsis lees paub txog kev qaug zog tawg. Peb xa hauv 6 lub lis piam-nrog rau qhov ntsuas qhov ntsuas qhov tseeb uas qhia txog 22% qis dua kev ntxhov siab ntawm qhov sib tshuam. Yuav ua li cas? Vim peb pab neeg no suav nrog cov qub twj tso kua mis tsim engineers uas tau thim rov qab-engineered tsis ua hauj lwm ntawm-site-tsis yog nyeem GD&T callouts.
A Stellite plug Hoobkas tsis tau txhais los ntawm nws cov furnaces los yog mills. Nws tau txhais los ntawm qhov nws teb peb lo lus nug: Yuav ua li cas thaum cov khoom heats li thaum kawg sib tsoo? Qhov twg yog qhov tsis muaj zog ntawm cov ciam teb zaum ntawm lub ntsej muag sealing? Thiab - qhov tseem ceeb tshaj plaws - tus neeg siv kawg ntsuas qhov twg hauv thaj teb? Peb teb tag nrho peb ua ntej txiav thawj nti. Tias yog vim li cas peb cov ntsaws ruaj ruaj mus rau hauv dej hiav txwv tswj li qub tau ntsuas rau 10,000 psi, lub tshuab hluav taws xob siab siab hauv cov tsheb thauj khoom tsuas, thiab cov twj tso kua mis precision tuav cov khoom siv polymer slurries. Tsis yog vim lawv ntsib cov specs - tab sis vim lawv muaj sia nyob cov xwm txheej specs tsis npog.
Saib tom ntej, peb tab tom nthuav peb lub peev xwm hauv hybrid casting-machining txheej txheem rau cov rooj sib tham loj ntawm Stellite-xws li monolithic valve lub cev nrog cov rooj zaum ntsaws ntsaws rau hauv ib lub ncuav, tom qab ntawd ua tiav hauv ib qho kev teeb tsa NC. Cov ntawv pov thawj tseem tab tom ua rau API 6A thiab NORSOK M-650 ua raws. Tab sis cov tub ntxhais tseem tsis hloov pauv: tsis muaj ib feem tawm ntawm Qingdao tshwj tsis yog nws dhau qhov kev sim ua haujlwm zoo ib yam li lub rooj sib txoos zaum kawg. Yog tias koj daim ntawv thov xav kom tsis muaj kev cuam tshuam rau kev yaig tsis kam, qhov ruaj khov, lossis qhov sib xws ntawm metallurgical - koj qhov txuas ntxiv ntawm Stellite pib ntawm no.
